The banches of life appearing during the Franceville era weren't less viable than the ones appearing in the Ediacara fauna. If oxygene levels today would drop below 10%, multicellular life would probably be as endangered than it was 2.1 billion years ago.
There have been multicellar livings before, like the Gabonionta, about 2.1 billion years ago, which existed for about 200 million years and have died out again.
Yes, the U.S. helped very much to make 1989 happen, but not by giving speeches on the safe side of the Wall. They made 1989 possible by being much more successful in economics, building the much better cars, the better computers, creating the better clothing and the better movies and music. They helped by bankrupting the Soviet Union which was awash in oil money in the 1970ies and early 1980ies, by forcing the oil price down and getting the Soviet Union to waste their money in an arms race.
But at the same time, the U.S. made things worse by supporting every dictator who was crying "I'm against communism" loud enough. It made things worse by toppling democratically elected governments if they weren't anti-communist enough. It was easy for the communist propaganda to point at South America or Southeast Asia and say: If you are supporting the U.S., you are supporting Imperialism and suppressing people.
Quantum mechanics were proposed by Max Planck in 1900, 1905 it was used by Albert Einstein to explain the photoelectric effect (for which he got awarded the Nobel price in 1921), and by the 1920 it was already heavily reworked and modified by the works of people like Erwin Schroedinger, Werner Heisenberg, Louis de Broglie and Max Born.
So Relativity and Quantum mechanics are quite bad examples for what you want to say. They were adapted very quickly instead.
The fact that we need a court to decide that "embedding a copyrighted YouTube video in your site is not copyright infringement." is already a failure of the system as a whole.
No, that's one of the things a court is for: Clear up legal facts if they are not explicitely stated in the law. The E.U. copyright directive and the laws in different countries don't mention embedding, and thus a court decides when the question comes up. In this case, the system works exactly as it is supposed to be.
The flow chart is a most thoroughly oversold piece of program documentation. -- Frederick Brooks, "The Mythical Man Month"
